| 摘 要： | 超声波已成功在医疗、化工和无损探伤等领域得到广泛的应用。根据超声波在空气中的传播速度会随着温度改变而改变这一特点,本文把空气中的温度场作为研究对象,利用超声波信号在空气中的渡越时间参数TOF(Time of Flight)来对空气中的温度分布情况进行超声波CT画像的重建。

| Abstract: | Ultrasound has been successfully applied to medical,chemical and nondestructive evaluation(NDE).Based on the variation of sound velocity with temperature,the temperature in the air is measured by the ultrasonic time of flight and the temperature distribution in the air is reconstructed by ultrasonic computerized tomography(UCT). |
